i TO ALL WHOM IT MAY CONGERNL Y,

Be it known that LUJOHN W. POST, of Castile, in the-county of Wyoming, and Stateof New York, have t invented a new and useful Irnp1m"en1entl in Skates; and I do. hereby declare the following to be a'full and correct description of the' same, suiicient to enable others skilled inl the art to which my invention 'appertainsto fully understand and use the same, reference beinghad tothe accompanying drawings, whichmakc part of this specication,. andin which- Figure 1, sheet 1, is a. side elevation of my improved skate, and

Figures 2, 3, 4, 5, 6, sheet 1, and 7, 8, 9, 10, 11, 12, 13, 14, 15, sheet 2, are detached views o f parts ofthe same, asherenafter xnore fully described'and referred to. i u

Like letters of reference indicate'like parts in theseveral figures.

The nature of-my invention consists in thepeculiar construction'oi a skate, so that by the use of on'e iever only the sa-me maybe attached 'instantaneously to the foot, without straps, and without the necessity of any 'plateor other contrivance in the heel, or anyV other part of the boot, to assist in. holding theslate to the foot.

A, inthe drawings, represents a skate-runner, having three elevations or standards, B, C, and D, ca'st or otherwise formed in one piece with the runner. Straddling the standard B, andrattached toit byel screw, a, is a bracket orsupport, E, provided rwith a slot, e, and two anges, t ande, which latter are provided with holes, bl'cl, into which screws 62 c2 t,by means. of which the heel-plate G is secured on the bracket E. The slot e, in the bracket E, has 'a cross-slot, e', in which the shoulder f of the .screw F has its bearing. This screw has a smooth stem, jits threaded part working in a sleeve, al, provided with a projection, d', which projects through zi'slot,1g, inthe heel-plate, and which forms a bearing for the forked lever G. This lever G has a serrated or toothed ,pivoted end, g1, the other end being bent, as shownat 92.1, Attached to the standards C andD is the foot-plate H, which, in its rear part, has a'slot, It, into which the'bent end Pof the lever G fits. Y The footplate H is secured to the standard C by means of' the bracket I, constructed similarly to the bracket E, with a. single difference. Instead of the upper edge of the standard being cut outras that of 'the standard B, (see fig. 6,3 it is lout out in V-shape, (see iig. 15,) the inner face'of the straddling-bracket I-being. shaped to correspond tothe V-shaped cut.l By this arrangement, the foot-plateH is not only supported by the bracket I, but also rests on thel edges z' of the standard G-a very important result, as it is very necessary, in skates of this kind, to have the foot-plate immovable on the standard. v

Fig. 12 is an end view of the standard C, bracket I, and the footplaite H, when the standard is shaped as in iig. 6, and the foot-plate rests on the bracket alone. Fig. 14 is a vertical crossesection in line w :11, iig. 13, and shows the pointof the angle of the V-shaped cut at z'. i

t -Figg 7 is a. top view of' the foot-plate Il, which is provided with two slots, K. These slots have a. part of their rear edges serrated, theremainder of their edge'srbeing perfectly smooth. L, gs. and 9, represent clauipi plates, which slide under the foot-plate, and are secured to the same by means of a set-screw, Z, passing through the slots K, downward into the hole Zi of the clamp L.

Kis a spur, pointed at the rear, and fiat atA the-front side, formedl on theA inner edge of the clamp L, and as long as the slot K is wide across the serrations. This spur fits into theserrated slot K, securely holding the clamp, its point passing into one of the serrations in the slot'.- .By this means the clampplate cannot move side= ways, and when it is desired to shift Jthe clamp, the screwZ need only be loosened suiiiciently to allow the spur K to be shifted into another serration, when, by tightening the screw Z, the clamp is again securely and firmly held in4 place.

In figs. 10 and`-11, a modification of the lever-device is shown. In this modification, the projection d on the sleeve d is -a pin, and forms the pivot for `the lever G', provided with a h olc, g3,.which passes over the pin d. The lever has a cam-shaped rear elevation, m, provided with grooves, n, whichV form semicircular cutting-edges, a, which, when the lever is turned in line with the foot,seize into and securely hold the heel of the boot, as shown in iig. 10. The lever is secured to the foot-plate in the manner already described.` The clamps L need be set to the boot but once, as Vthey will fit then always. Y

` To attach the heel by the lever G', asshown in iigf, the lever is lifted fronti the slot h into the position shown in red lines.` The front part of the foot being between the. .clamps L, the heel is put down between the brackets p, formed on the heel-plate Gr, and the lever=Gr raised into position, as shown in black in g..1. This movement has two results. 4The lever {iQ-moving on'a pivot, has a circular motion, so that by`foroing the teeth into the innerside of the heel, the latter` is not only pressed back against the brackets p, but also downwards on to the heel-plate G, thus forming a firm-aud secure fastening.. -WhenV the lever G, shown in fig. 10, is used, the cam-shaped end of the same forcesthe heel back against the brackets p, the edges seizing 'into and securely holding the heel. vAfter or before` the lever G .is secured, the same may be se't to any size heel by means 'of the screw F, which moves the sleeves d, bearing the levereitherforward or back, as desired. In' this skate-fastening there is nothing to be done to the boot; no hole bored into the heel, no plate to be let .into the same, an'd the skatev can be puton arid fastened uone moment.- V

i Having-thus described my invention, what I claim as new therein, and/desire to secure by Letters Pateutyisl.v The heel-fastening, consisting ofthe lever, pir/Loted on a sleeve, d, and made adjustable by means of the set-screw F, substantially as described.

f2; The pivoted lever G, having a serrated rear vface,and secured A.to the foot-plate H, substantially as set forth.

' 3. The device for adjusting the pivoted lever G', consisting "of thesleeve 0;?, :moved-bythe setfscrew F, pro. vided with a' shoulder, f, which has `its bearings in the cross-slot .of the slot e, in the bracket E, substantially as described.

4. .The clamps L, provided Vwith spurs 7c', in combination with the partly-serrated slots K, substantially as 'and for the purposes described.

5. The V-shaped cute' in the standard 0,aud the correspondingly-shaped bracket I, vsubstantially as and' 'for .thepurposes set forth.-

The above specifca'tion of my improvement in' skates signed, this twenty-second vday of January, 1868.
